The ectopic thyroid
tissue with submental localization has not been sufficient to prevent development of clinical hypothyroidism.
This case presented to us with respiratory distress due to tracheal compression by the ectopic thyroid
tissue in the thyroglossal cyst duct: Rare clinical entity with review of literature.
KEY WORDS: Ectopic thyroid
tissue; Vascular variation; Midline cervical mass.
One of the pediatricians suggested that it could be ectopic thyroid
tissue; however, no medical tests were performed.
Stopping thyroid replacement in patients with lingual or sublingual ectopic thyroid
tissue is not recommended because of the possibility of airway obstruction caused by enlargement of the tissue under TSH stimulation.
Lesions involving ectopic thyroid
tissue were excluded.
Ultrasound of the neck would have been useful had there been concern that the mass represented ectopic thyroid
tissue, but this was thought to be unlikely given the mass's appearance, location in the anterior tongue, and consistency.
However, the pathologic specimens of the patient were investigated again by Pathology Department of our hospital and ectopic thyroid
tissue and thyroid adenoma was seen.
tissue can be found in unusual circumstances contained in central compartment of neck, posterior part of tongue, under lower pole of normal thyroid and occasionally in anterior medi-astinum.
A 99m Tc-pertechnetate thyroid scan showed a normally located and functioning thyroid gland as well as midline ectopic thyroid
It is children born with ectopic thyroid
glands or defects in hormone synthesis (thyroid dysgenesis or hypogenesis) who are at risk of being missed in screening because their T4 levels may initially appear normal and only fall some weeks or months later, he noted.
